Do you know any men who at public restrooms choose to urinate into toilet bowl INSTEAD of using urinals.

Is there any kind of hidden shame/ostracism you experience from other users of the premises. Is it RARE to use the toilet bowl versus the urinal. Why do they do this. Are they afraid of being checked out by other guys? Girls dont have a choice so it is strange to us (and a complete PITA). Are guys ever so nervous they cannot pee when others are in the restroom (I actually KNOW girls who cannot go when others are in the same room).
